I did cosim of my amplifier and it is working fine. The currents at the transistor pins are right. But the total current drawn from the source is 3.3kA .. Why this must be happening? Any ideas? and whats the solution?
A widely used simulator suddenly gives unexpected results.
Please tick an answer:
[ ] simulator is broken.
[ ] modelling mistake.
How can you expect help if you don't show/upload your model?
If this is co-simulation, my guess is that you made the usual mistake: DC not included in EM model frequeny range, so that ADS uses extrapolation from GHz to DC. This would show a clear warning in the simulation. Show what you did, and we don't have to guess.
